The AS handle MAIN-SEQUENCE-TECHNOLOGIES is held by Main Sequence Technology, Inc.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS entries such as host64.pcrecruiter.net and host190.pcrecruiter.net within the 68.171.3.0/24 block.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 2 IPv6 prefixes, with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

  • Registrants are mixed: 68.171.3.0/24 is registered to Main Sequence Technology, while 207.220.83.0/24 is registered to Level 3 Parent, LLC, suggesting a lease or historical allocation.
  • The inventory consists of two distinct IPv4 /24 blocks and two IPv6 prefixes, reflecting a modest, segmented corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
